Summary of Changes

Yak-41M Planned production version with added anti-ship capability. 2 flying prototypes built. Production aircraft would have had uprated R-79M engines and flight refuelling probe. [Izdelye 48M] http://www.aeroflight.co.uk/tag/yak-141

In 1977, even before service introduction of the Yak-38, the go-ahead was given for development of a supersonic jet VTOL fighter, the "Yak-41". Once again, four prototypes were built, two of them being flight prototypes. Development was protracted, partly because of redefinition of the aircraft to a multirole configuration, the "Yak-41M". http://www.airvectors.net/avredvt.html#m3 Other source : Name of four prototypes (Izdeliye 48-1~3, Izdeliye 48SI) https://russianplanes.net/planelist/yakovlev/yak-41/141

  3. Properties Night Navigation (Ferry, Air-to-Air, Air-to-Surface Missiles) Bombsight - Advanced Computing Helmet Mounted Sight / Display (HMS/HMD) Probe Refueling

The Yak-41M featured much more modern technology in every respect than the Yak-38. About a quarter of its empty weight was composite assemblies. It also featured an advanced avionics suite, including Zhuk Doppler radar, like that used on the MiG-29 but with a smaller antenna; a digital fire-control system linked to the radar and a helmet-mounted sight; a modernized navigation system; and a digital fly-by-wire flight control system. The flight control system performed diagnostics on the machine and would not permit take-off if a serious failure was found. It would auto-eject the pilot if a failure occurred in flight, and the main engine nozzle was 30 degrees below the horizontal. http://www.airvectors.net/avredvt.html#m3
